Sleep uses more power than I expect

hibernate

When my new Dell laptop with Windows 7 Home Premium and 4GB RAM sleeps (not when it hibernates), it will drain the battery overnight.
My old Dell laptop with XP Pro (2 GB RAM) could sleep for days without running out of battery.

Is it normal that Windows 7 sleep is this power-hungry or should I troubleshoot my new machine?

Edit: I know how to set the different sleep/hibernate settings. That is not what I'm asking.
